1983 R80RT gas mileage
1983 R80RT gas mileage
The RT is performing well. Sometimes the idle will hang at about 2K rpm. Riding seems to be the cure for the hanging idle. Plugs are showing on the rich side. BP6ES plugs.
I have considered going to a DynaTek coil, but I'm not sure which one would work. Also, I don't know whether to use the resistance or non resistance wires, caps and plugs. I figure that a stronger spark would help the mileage.
I will check the valve gaps. I suspect they will be OK. Total miles on the bike is 23,800.
I would be appreciate any feedback.
Cheers,
Bill

The plugs dont look to bad.
I went for a ride on my 92 other day with other guys. We were going 40-50 mph, 140 miles I got 40.75 MPG. And I was bored...last man.
Ethanol gas with additive for water control.

Not sure if you were running
- valve clearances
- carb health and state of synching
- position of carb floats...they might be too high resulting in rich operation
- tire pressures
- final drive proper for the bike; RPMs might be higher than expected for given MPH
The stock ignition system should be just fine...I'd wait to throw money at this until you're sure of the state of tune. The bike should use zero resistance plugs and wires...the spark plug cap has a built-in 5K ohm resistance. Adding more resistance will make the spark weaker and it might misfire if the state of tune is marginal.
This page:

suggests that the gas mileage should be in the low 40s.

Fast. Neat. Average. Friendly. Good. Good.
I added the BG before the
First thing I will do is check the valves. It's cheap. Then more after that.
Thanks,

If this was the first time
Got the valves
Is there a connector for a carb sync on my Bings?
I saw the spec online. Informative.
I kept the bike running through the winter. I had a good tank of gas for my little trip. 91 octane, fresh.
EUBMW in Alexandria, VA has carb kits. I’ll want to see if anything is obviously amiss before I buy anything. Yes, I should check the float height.
Thanks,
Bill

With the idle RPM so high, it

Two cams - "Another thing
"Another thing is the Governor weights inside the "can" hanging up? Oak had talked about them in one of the Airmail Magazines."
I thought my ignition was electronic. Does the weights problem still apply?
